12v battery charger? Answered

My WiFi ISP signals were unable to reach my room. So my ISP arranged a device  on top of apartment & it was powered with 12 volts DC adapter. But makes me to work offline when power is OFF. So i want to make that device to work on 12V battery. So i need to make a charger for that battery to work as UPS. Can any one help me with circuit Diagram and components list??

Get a standard UPS for the power line and plug the 12V DC adapter into the UPS.
